OPERATING DEVICE FOR CHURNS.

Application filed January 20, 1920. Serial No. 352,723.

tains to make and use the same.

The invention relates to churns and has for its object to provide a churn having a rotary agitator therein whichagitator is in termittently rotated to the right and to the left, and also to provide an operating mechanism for the agitator comprising a shaft preferably vertically disposed in a framework. The shaft has secured thereto near its upper and lower ends bevel gears, which bevel gears are intermittently engaged by teeth of a multila'ted rotatable gear, which gear when rotated will cause its teeth to engage the bevel gears of the vertical shaft and as the bevel gears are rotated in opposed position said shaft will be reversed in its rotation as a horizontally pivoted driving gear is rotated.

A further object is to provide adjusting means whereby the driving gear may be adjusted in relation to the bevel gears carried by the vertical shaft.

l/Vith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a side elevation of the churn and its operating mechanism.

Figure 2 is a front elevation of the churn, the receptacle being broken away to show the churning element.

Referring to the drawings, the numeral 1 designates a base to the ends of which are secured triangular shaped uprights 2 formed from strap iron. Secured to the apexes of the uprights 2, as at 3 are arms 4 of a U- shaped frame 5. The parallel portions 6 of said U-shaped frame 5 are braced relative to each other by means of cross bars 7 The upper end of the U-shaped frame being provided with a hand grip 9 formed from the same piece of strap iron that forms the Ueshaped frame Sand by means of whichhandle the frame as a whole may be braced during a churning operation. Rotatably mounted in bearings 10 of the braces 7 and S is a shaft 11. secured to its upper end a bevel gear 12 and also secured to said shaft near its lower end is a-bevel 18, said gears being adapted to be rotated so to rotate the shaft.

Shaft 11 has The lower end of-theshaftll' has secured thereto a sleeve 14., said sleeve being rotatably mounted in bearing 15 of the can cover 16, said can being designated by the numeral 17. Detachably carried by the lower end of the sleeve is an agitator 18 which is disposed within the can 1? and is adapted to be rotated during a churning operation. ltotatably mounted in a bearing 19 of one of the arms 4 of the frame '5 is a shaft 20 to which shaft a gear 21 is secured. Gear 21 is provided with segmentally arranged teeth 22 which teeth do not extend quite 180 degrees around'the gear 21; therefore it will be seen by referring to Figure 1 that the portion 23 of the gear 21 is not provided with teeth, and it will be seen that as the teeth 22 are in mesh with the teeth of. the gear 13 that the blank portion 23 will pass by the gear 12. However,

by causing an intermittent rotation of the agitator 18 in one direction and then in the other.

. :To prevent the overthrow of the agitator and to brake the momentum of rotation of the shaft 11, a pair of spring actuated detents 24 are provided, which detents frictionally engage the upper face of the gear 12. It is to be understood that frictional gearing may be used in the place of bevel gears 12 and 13 if so desired. An adjusting sleeve 25 is threaded on the shaft 20 and is adapted to be threaded inwardly and outwarc ly' to adjust the gear 21 in relation to the bevelgears 12 and 13. Thisadjusting sleeve is particularly advantageous where frictional gears are utilized.

Agitator. 18 comprises a member having vertical slots 24: and to each side of the member is secured an inclined bar 25 which are adapted to act as agitators during a rotation of the agitator 18.

From the above it will be seen that a churn is provided wherein an intermittent rotation'of an ti; ,'itati11; element in both directions is provided and one wherein the gear elements may be easily and quickly adjusted relative to each other.

The invention having been set forth what is claimed as new and useful is v An operating mechanism for agitators of churns comprising a frame work adapted to be disposed over a churn, a vertically disposed shaft rotatably mounted in bearings of said 'flil'lllfi work, a horizontally disposed rotatable shaft mounted in said frame work,

spaced bevelled gears secured to said vertically disposed shaft, a segmentally shaped gear carried by the horizontally disposed shaft, said segmentally shaped gear being adapted to mesh with the teeth of the bevel gears alternatingly to impart revoluble movement to the vertically disposed shaft in one direction and then in the other direction as a continuous rotation in one direction is imparted to the horizontally disposed shaft spaced vertically disposed spring actuated detents, said detents engaging the upper side of the upper spaced bevelled gear at opposite sides of the vertical shaft and having their lower ends in sliding engagement with said bevel gear, and a handle member carried by said frame in axial alignment with the ver tically disposed shaft and having its gripping portion in parallel relation to the horizontally disposed shaft.

In testimony whereof I have signed my name to this speclhcation in the presence of two subscril'nng wltnesses.
